Abstract (en)
[origin: EP2518027A2] An electrode holder (10) for use in a furnace for melting a batch material to form molten glass is disclosed comprising a refractory coated nose member (16) presented to and in contact with a molten glass material contained within the furnace. The refractory coating (46) is preferably a flame- or plasma-sprayed ceramic such as alumina or zirconia. That protects the nose member (16) from corrosion from the hot molten glass. A method of forming a molten glass comprises heating with an electrode (22) positioned in the inner wall (14) of the electrode holder (10) and the flowing oxygen-free gas between the inner wall (14) and the electrode (22).
